FOR ALL: Every year at the beginning of summer and continuing through the hot months- people start messaging me about v***r lock(hard start, flooding, erratic running etc)- especially in mtronic saws- but also regular carbs and auto tune...
The short answer is, I don't have any miracle cures. Keep it out of the sun. Take extra breaks between big cuts to let things cool off. Ensure your tank vent, gas caps (the o-rings matter!!!), air filter are all clean and functioning. Try relieving cap pressure. You MIGHT try replacing the solenoid if you're having excessive issues but it's likely not the culprit solely.
I've seen milling guys try running re-fuels (not advised for safety) and people trying different fuels, full throttle starts etc... unfortunately I don't have a good, reliable, safe answer... This time of year, saws get finicky so you might want a backup!!! If you have any tricks for your fellow sawyers, post them below!!👇
