I have a toro 20067 with a Briggs 6.75 hp engine with electric start. Its been harder to start this summer. Seems to take extra priming. I ordered a carb kits which came today. And as it was, I couldn't even get it started today, with starter or pull start. So pulled off the carb and rebuilt it checking all orifices and main jet holes. Put back together and would only start if I plugged the carb inlet with my thumb. Started and ran fine. Could see pulses of fuel as it ran. Pulled carb and checked it all over again and still the hard starting.
I checked the spark and did get a blue spark, I guess it looked strong enough. Would it b hard to start in this manner in the spark was weak? Any way I can be sure it's strong enough?
It did start after some messin, without my thumb, but more priming than it should take. I did pull prime bulb and it is in good shape. When I do prime, I can see some fuel being pushed up through the brass tube in the carb. Any help on what I can check. Thanks.
