So, I've been asked to look at a friend's 3500S (Fed model). It feels a little under-powered. Set up is as follows:
I've found rectified the following:
The ignition timing seems good with no scatter (I know the timing chain/sprockets wear on these engines), I can't tell if the cam lobes are worn, but with so few miles on the engine I'd be surprised if they were. Idle is pretty smooth at 650rpm.
Can anybody think of something I might of missed?
Many thanks,
Steven
- 1970 3500 engine with SD1 cylinder heads
- Rebuilt in last 2-3k miles by persons unknown.
- LT77 5 speed conversion
- HS6 carbs with dodgy manual choke conversion (no AED now)
- Mallory dissy and electronic ignition.
I've found rectified the following:
- Replaced crumbly HT leads (spark plug wires)
- Tuned carbs as best I could (see follow on) - found one needle set inside piston on one carb. Idle set on other carb with fast idle screw. Needles are BAK
- Replaced all vacuum/breather hoses
- Replaced spark plugs (They're not bad, but as I was there)
- Set ignition timing
