It is a boggo 1600 t1 engine type.wonder if you folks can help me spot the obvious here? I keep the engine in good service and use it daily. AS' engine its a good strong engine, however recently changed the oil and adjusted the tappets - 0.006 inches as read on a website somewhere that recommends this for later engines? Well I think its running hot, hotter than normal, exhaust is really hot! Dipstick test seems to be ok but exhaust heat can be felt on the tinware. Its lost a bit of power I feel and does not go as well or progressively as it did? This morning I readjusted tappets to 0.004 inches as usual but it still feels the same? I wonder if I have got my timing wrong on the flywheel? My dizzy has the mark facing towards the engine not out as I would expect? There are more than 1 marks (previous owners I expect) so When I did the timing I tried to be as accurate as I could using the marks that seemed to fit in with bothh sets of valves open as best I could. The thermostat has been fine and the flaps all work fine. So I wonder if the the timing is out maybe the engine is running a bit lean and therefore getting hot? This is all i have done other than oil change?
Could you repeat that in English please. Specially this bit: I wonder if I have got my timing wrong on the flywheel? My dizzy has the mark facing towards the engine not out as I would expect? There are more than 1 marks (previous owners I expect) so When I did the timing I tried to be as accurate as I could using the marks that seemed to fit in with bothh sets of valves open as best I could.
Sometimes the pulley has more than one mark for timing and are on the engine side of the bottom pulley...is this what you meant? To find TDC try taking out no 1 spark plug and poking a pencil down and turning pulley until poking out the most which will be TDC so youbcan tippex the right mark on the pulley, but make sure you don't snap the pencil!! Cheers Ben
Sorry been a very long day full of a cold! Start again. The dizzy body has a mark that you line up with the rotor arm against at the same time as the chip in the flywheel that lines up against the crankcase joint. This should be your starting point then you turn flywheel anyiclockwise for each cylinder etc etc. The mark on the dizzy is set pointing towards the engine rather than towards you(I seem to remember it normally facing you rather than this, but my memory might be hazy? Anyway the mark on the flywheel does not line up well with the dizzy, and there are more marks on the flywheel probably previous owners? I have no history of this engine? Could be a rebuild for all I know? Should I assume the chip in the flywheel is correct and adjust the dizzy to line up with the dizzy bodies mark ? Then take it from there for the tappet line up? Is there a sure fire way to find the correct starting point, assuming these marks are a pile of rubbish?
The pulley (it isn't the flywheel) will be correct - it's keyed onto the crank, so it can't be wrong. Try rotating the engine 180* and see if the dissy mark lines up. Don't forget there are two TDCs for no 1: compression and exhaust stroke. To set the tappets (assume you're doing this), you need to start on the compression stroke. Are you doing tappets, or timing, or what?
Perhaps mate you could /would try slightly adjusting the dizzy, running bus ,see how she feels/performs, and readjust from there,alt. take a deep breathe , put dizzy where you think it should be(5 o clock?) and try 2 start her up , my own bus took a fair bit of rough running before i settled on the current settings , best fuel,engine temp, acceptable performance,sometimes your own opinion, at the coalface , so to speak is the best one, and as you said , bus was running ok recently.
Thanks for the help , sorry not explaining well , yes pully not flywheel , like I said not quite 100% at the mo, best leave it until feeling better knowing my luck will mess up a good motor! I tend to set up then listen to engine and go for a short run, tweak then try again until it feels right, bus always manages to tell me how it feels( know that sounds odd but they do talk to you unlike modern cars!) Even now it pulls well and fires on the button just think I have messed up the timing?
perhaps a dumn question but i"ll ask it , you got a timing lamp? if yes hows things looking? if no , back to what your ear tells you, or find a local private "dude" garage and ask for a quick "plug in and point" check, for a couple of bucks . My own bus runs "hot" re same as you said re tinwear on yours , but i do tend now to tune by ear,and ive nailed the valves at oo6.BUT, thats my choice. Daytime soon , some guys on here will ,no doubt advise a fix 4 you, good luck.
Set your tappets properly, set the contact breaker gap properly, then do the ignition timing statically with a light bulb or time it with a strobe. You can't set ignition timing "by ear" - you'll cook your engine
Points, plugs set up correctly, no I dont have a timing lamp, but they are cheap enough to buy online these days. Thank you again for your advice, I've never cooked an engine yet but its best to be safe.
i can assure you mate you ,or at least i , can and do set my engine by ear , it , or rather my bus , is an old ,almost agricultural vehicle ,the possibility for engine cooking certainly exists, but with the time and a gentle touch ,well, my bus is sweet.i started asc a kid being shown to set by sound, moved to lamps or whatever, and am more trusting of my own opinion on how my machine is responding to my spannering. a.k.a.> another "skill" on way of the rest of them ,soon , no campers/classic vehicles on road cos all the timing lamps were confiscated.like torqeing without wrench/doing valves on"the rock"
please dont think i wanna do that " your wrong, i"m right" gig , my experience, anyhow , is , i more trust my own senses, feel how she is running/responding to my adjustments, granted i keep mine basic/simple , i do see and appreciate your very real points , what with taking into account wear thru the systems, i"m happy with what i"m running at the moment BUT!!given the cash and trust /recommendation(s)i would have it on a rolling road , tune /set it up system before you could say "your ear not working ?"it"s just that sometimes i throw the text books out and resort to the"old ways " (i am old !) respect 2 you and your opinions and all.did not mean to offend you.
