Re: 90 e-ton bogs and won\'t run
If your mini has a Spark Arrestor on its pipe, remove this spark arrester and clean it. For now (to isolate this problem), keep the spark arrester removed.
If you replaced the factory air box with an After Market Air Filter system, you must re-jet the carb. This is a must!!!!! As as suggestion, re-install the factory air box and ensure NO leaks around the carb's intake and factory air box.
If your mini has one, replace the inline gas filter. This gas filter should be changed every year. If it has factory crud in the gas tank, it may have to be changed after factory burn in. re: After the 2nd tank of gas.
Install fresh gas. If wondering, gas starts to loose "its punch" 25+ days from its pump date. If your gas is more then 25 days old, install fresh gas. Also, gas will naturally condensate this time of year. Especially within Ontario Canada Spring weather. Thus, there may be some water in your current gas. As a suggestion (even for peace of mind), install new gas.
Note: If within the burn-in period, don't use 50:1 Pre-mix in the 1st tank of gas. It's much better to use 100:1 Pre-mix for 2 full tanks of gas. Especially if your mini came with a factory Spark Arrester. Also, ensure the premix oil and factory Injection Oil is a brand "you trust". If necessary, dump the oil in the OI tank and install the brand you know will work. For example: Motul 600 Synthetic Blend.
