Hello all,

I was lifting with my bucket on my sweet old MF165 today - heavy load and revving about 2000. The engine started missing and then backfiring (very loud) and I had to cut down the throttle and it caught up and ran again for a while. It got worse and worse until it was basically impossible to run.

I figure it must be missing spark and letting fuel into the exhaust and hence the back-fire when it gets spark again. BUT, I don't know what to check. I am not sure how to check the points gap or how to know if it is firing at trhe appropriate time. I cleaned and lightly sanded all the contact points on the rotor and distribiutor cap.

I welcome any assistance on this. Thanks.
