Advice Please.
I have just rebuilt engine for 1933 RP.
Runs very well etc except for two minor problems.
I would welcome any suggestions from people more experience and knowledgeable than myself regarding these two issues.
1) The tickover is a little too fast. The slow running stop is screwed so there is no contact with the operating leaver, ie that is not the cause of the fast idle. Similarly, when choke is fully off, the screw that bears on the choke leaver that opens the throttle is also not in contact, so again, that cannot be the cause of the fast idle.
The only way I can slow down the tickover to a more reasonable speed is by retarding the ignition to almost TDC
Any ideas?
2) When revving fast, there is the (very) occasional spit back through the carb.
The plugs appear black, not wet, not sooty.
Again, any ideas how I can remove the spitting problem?
best regards
