thanks you !!!Only engine I know of for the 1830 was a Renault Gas about 30hp. The 1835 which was the next model and replaced the 1830 had a Case 188 diesel also about 30hp. The renault gas motors were hard to keep servicable and many of the units were junked for that reason. Could be a swap was done and they did a good job. I didnt look at your pictures because the site you posted them on is all about phishing.
