FB Falcon 87

Post  taffgmg on Sun Nov 06, 2016 11:05 am

I have bought a1960 Falcon 87 off a chap that used it just for club runs. (AMC engine)

Starts first kick generally and ticks over fine.

Gets to about 30mph fine but then starts too lose power and 40mph is flat out.

Is this to be expected of should it go faster.......only plan to use it locally so if that is it thats fine....

What should I check and more specfically what order should I check in - don't want to pull the engine apart if it is potentially something simple.

Thanks in advance!

Poor running

Post  kerabo on Sun Nov 06, 2016 12:41 pm

It should run lots better than that. It should reach 60ish  or more.
Check the basics first
is it getting full throttle
Has it got a good fuel supply through the tap, the pipe and the float level valve.
Is the air filter blocked.
Is the silencer blocked if it's only done short low speed runs

It might be that you may have left your choke on this would restrict it, check your plug if it is sooty then it running rich,but as Ken as said worth checking the basics first keep us updated, it can be difficult to solve a issue,but I would check
1 plug
2 timing
3 Carb
4 fuel
What oil petrol ratio are you using?
