| ht eonly times you should remove the plug is if you flood the engine or it dies
removing it and putting it back in will give you a crap seal cos when its tighted from new it squishes the washer to make a seal
and heating the block up only losens the piston and liner when they are new beacuse it is still tight
also for the car engines if you can try not to use model technics fuel as its crap
good fuel to go for is tornado but there is a few others like o donnels which is good also |
