I’ve recently starting having a backfire when letting off the gas, mainly in third gear and when I come to a stop it wants to stall. It will idle fine but if you rev the engine and let it return to idle it stalls out. Any ideas where to start? Timing, carb, exhaust?
Thanks
1969 series 2a
2.25 gas
Electronic ignition
Check Idle RPM's, is setting screw set to low?
Timing, is Ignition timing correct?
Look at filters, are they clear? Does carb have a filter?
Plugs, are plug gap correct?
Could be a myriad of items, choose one and follow through.
Possibly a slight air leak, carb. to manifold or manifold to head.
vacume advance? often though it's vacume leaks.
+1 on this post. Think about the engine as a chain. Look at each link in the chain and rule it out.Quote:
