Got my engine back from Rcingnitions and it ran but had low end carb surging and dieing. Was kinda discouraged and then thought about my DA 150 that needs to be sent in for crash damage. I took the carb and swapped it. Good fit and I did have to open the gasket a little where the pulse hole is. The engine started and ran through the high to low end pretty well. Took it to the field and did some minor adjusting and flew. This is the first flight out of 15 that the engine ran the whole tank without stopping. Did a litlle more tunning and flew again. It was O.K. all the power is between 1/2 and 3/4 throttle with less than 200 rpm btween O and 1/2. Will have to get used to it I guess. Any body got RPM # for top end? I tached 5680 on 32-12 PT prop. Can more be had with the original carb? Is it worth it to buy another Tillotson carb or just stick with the Walbro carb fron the DA? Hello is anybody out there???????????
