if the dizzy is in 180 off .. you can re-index the plug wires on the cap to compensate.. but that's not really right as that might add confusion in the future. ( Hey !! that's what's wrong with the whole world ...'confusion'. There , we nailed it...humanity's main problem ..Confusion ) additionally on an air-cooled VW opposed four ( yuck ! btdt ! ) # 3 is slightly retarded on the points cam, and it would not really be right that way, though it would run just fine. on a Fridae maybe I'll share a 2,500 year old buddist thing about 'confusion.' Just a paragraph. I know it by heart ...it is really a 2,500 year old thing. How many vanagon techs know that kinda stuff too ? seeing more clearly now, Scott On 12/7/2013 11:48 AM, Steve Cotsford wrote: > Thanks for your comments Scott. I must confess that my instinct would have been to remove the r/h valve cover and check the valve positions on #1 but I can see your point and reasoning. I have been working on overhead cam engines so long but clearly on this engine the cam shaft is a lot harder to look at :-) I should probably need to do that check anyway. As you say the Dizzie could have been put in 180 degrees off. > Cheers, Steve > > On Dec 7, 2013, at 2:17 PM, Scott Daniel wrote: > >> thanks for the reference .. >> >> one, I'd ask how is the poster totally sure he has the engine on # 1 TDC >> when the dist rotor points where it should. >> >> the only absolutly sure way to tell it's on t# 1 TDC to fire is to >> remove the left valve cover and see that # 3 valves are in 'point of >> balance' .that is exhaust just closing and intake just open .. >> when # 3 does that, and crank pulley says it's at TDC ..then you know >> it's really on # 1 TDC to fire. >> >> othewise you don't actually truly know.
