If the bulb is good it shouldnt cause starting problems. Give us a model number and discription of your symtoms and your starting procedure,maybe we can help.

--ok it was always hard to start since i got it.i took the flywheel off to check the points and found that the plate that the points bolt to had a lot of play in it.making the points open and close at the wrong time so i changed the plate,points .020,coils,plugs .030(ngk) ,wires,all new fuel line,water pump and lower end seal kit.the engine has great spark now and does not sputter anymore. did a compression test and got 63 psi on both cylinders.fresh fuel 50-1 mix<br />--- ok now for starting i pump the bulb till its firm put the choke. set the tiller arm to start position and pull and pull and pull about 8-10 times.once it fires off i take the choke off and it runs well.once hot i can start it with a half pull every time.<br />--i have never decarbon the engine and was going to try that next.i was also told to get champion plugs instead of the ngk. i never went though the carb or the fuel pump because when its running it runs great

decarbon the engine today.besides pissing off all the neighbors with the smoke. i gained a few rpms and had to re-adjust the carb. after i was done i changed the plugs with champion plugs and it starts right up now.i am not sure if that stuff cleans carbs out too but for 6 $ a can and alittle time it worked like a charm i did not run another compression test to see if i gained there but from what i seen in the test barrel there was a lot of carbon in the engine

Compression was kind of low 100lbs is considered minimum.<br />Folks have reported good results with decarb procedures.Ill bet compression is better now.<br /> Glad things are back to normal.
